Brother Bing, is this method scientific?

I think it is scientific.

Why the physical quality of soldiers is higher than that of ordinary people is precisely because they are good at exercise and diligent in exercise. Don't avoid the hottest and coldest periods of the year. The more these two periods, the more you should exercise. In the cold winter, if we exercise regularly, we can also improve our physique. Now many children are particularly afraid of the cold. I can't stand it when I get outdoors, so I have to go home at once. Staying outdoors for three or five days can also make our bodies adapt to the cold climate as soon as possible.

After exercise, all the cells in our body are awakened, and our lagging metabolism can be revived, which also determines people's health to a great extent. In dog days, most people will hide at home and blow air conditioning, but if they stay indoors for a long time, the viruses in our bodies will not be released, which will affect our health for a long time, and going out for exercise in summer can also make our bodies sweat and detoxify.

However, there are many precautions when exercising. For example, if you exercise for three or nine days in winter, you must keep warm. If you get frostbite, it's not worth the loss. Also remember not to exercise on an empty stomach. If time is tight and you want to exercise on an empty stomach, you must drink a cup of warm honey water before exercise, which can wake up your body. In addition, try not to choose in the dog days. Going out to exercise when the sun is hot at noon will cause heatstroke. You can choose the time after dinner for proper exercise.

For some elderly friends, high-intensity exercise is not allowed. As long as you exercise properly, your physical fitness can be improved.
